Patented May 27, 1930 UNITED STATS L'Zttt FFECE I-IIRAM BLOCK, OF BALTIMOREMARYLAI\TD PERMANENT-WAVING- TUBE Application filed September 12, 1928.

10 vision of a device of the above character in which electrically generated steam is utilized to effect the desired result, the construction being such that the hair is effectually separated from the source of heat used in generating the steam, so that the hair is not subjected to the dangers of dry heat, or the customer to scalds or burns, while danger of electric shock is also avoided, the operation producing a Wave of pleasing and lasting effect.

lVith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawings Figure 1 is a si-de elevation of the invention.

Figure 2 is an enlarged fragmentary sec- 0 tion partly in elevation of one end of the device.

Figure 3 is a similar view of the other end of the device.

Referring to the drawings in detail Wherein like characters of reference denote correspondin g parts, the invention as shown comprises an outer tube 1() which may be formed of any suitable material, such as aluminum or One end of this tube is threaded as shown at 11 and threadedly engaged With this end is a sleeve 12 Which is prefer'- ably formed of bakelite or other non-conducting material. The outer end of the sleeve 12 is provided With a flange 13 and engaged over this flange is a soft rubber nipple 14 Whose inner end is secured to the sleeve by means of a clamping ring 15. The outer end of the nipple is circumferentially grooved 5@ as shown at 16 for the accommodation of a clamp 17 by means of Which the device is at tached in position for use.

Located Within and spaced from the Walls of the tube 10 .is an inner tube 18 Which is perforated. rEhe end of the tube 18 adjacent the nipple 14 is open, While the opposite end of the tube 18 is enlarged to provide an outwardly flared stopper or closure 19 Which engages the adjacent edge of the tube 10 and forms a steamtight closure for the latter.

As thus far described, the device includes an outer tube 10 and an inner tube 18 which is spaced from the outer tube so asl t-o provide a cylindrical chamber Within Which steam is generated in a manner about to be explained. The tube 18 forms a hair compartment into which the hair is introduced through the nipple 14. The hair is first Wrapped upon a'inetal rod, spirally in the usual manner and is tied With a cord as customary. The hair upon the rod is placed Within the hair receiv ing compartment and the ydevice is clamped upon the hair by means of the clamp 17. This end of the device is thus effectually closed upon the hair.

The tube 18 may be formed of aluminum or other suitable material and is surrounded by a tube 20 which may also be formed of aluminum and both the tube 18 and the tube 2O are perforated as shown at 21. The perforations 21 register and these perforations are covered by a lining 22 of suitable absorbent.

material which is positioned between the tubes 18 and 20. rEhe tubes 18 and 20 and the lining 22 `thus form aninner tubular member which, as stated, receives the hair and is spaced from the outer tube 10 to provide a steam generating chamber 19a.

The outer flared portion 19 of the tube 18 an annular flange 29 which engages the cuter a serial No. 305,510. L, y

:910 1s provided With a reduced neck 23 which 1s edge of the neck 23, While a spring 30 acts to yieldingly hold the flange in engagement.

The hair upon the rod (not shown) is placed Within the tube 18 through the rubber nipple 14 and the latter is clamped thereon by means of the clamp 17. I-Ieat from an electric heating unit 31 Which is placed upon the outer tube 10, generates steam from moisture furnished by the saturated absorbent material 22. The hair is thus separated from the heating unit 31 by means of the steam generating chamber 19a, and is thus spaced from the dry heat of said unit. In addition, the rubber nipple 14 and the sleeve 12 effectually insulates the heating unit from the scalp of the customer so that all danger of electric shock is avoided even Where the outer tube 10 is constructed of metal.

Excess pressure of steam governed by the tension of the spring 30 will act to force the valve 28 from its seat so as to permit of the escape of steam from the inner tube 18, the stream passing outward through the opening 2 The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall Within the scope of the appended claims.

Having described the invention what is claimed is 1. A hair Waving device .comprising innerl and outer concentrically arranged tubular members spaced apart and defining an inner hair receiving compartment open at each end and an outer steam generating chamber surrounding the hair receiving compartment, said inner tubular member having openings spaced substantially throughout its length, an absorbent material between the hair receiving compartment and steam generating chamber, a source of heat for said chamber, a compressible ring at one open end of the device for the passage of hair into the hair receiving compartment, and means at the opposite end of the device to yieldingly close said end of the hair receiving compartment.

2. A hair'waving device comprising inner and outerv concentrically arranged tubular members spaced apart and defining an inner hair receiving compartment open at each end and an outer steam generating chamber surrounding the hair receiving compartment, said inner tubular member having openings spaced substantially throughout its length, an absorbent material between the hair receiving compartment and steam generating chamber, a source of heat for said chamber, a compressible ring at one open end of the device for the passage of hair into the hair receiving compartment, an outwardly flared extension at the other end of the inner tubular member to rictionally engagethe outer Vtubular member and close this end 'of the steam generating chamber, and a normally closed spring influenced valve at'the adjacent end of the hair receiving compartment.

In testimony whereof I affix my signature.
